10 Claims.

This invention relates to planters and more particularly to a direct connected tractor corn planter in which thecorn planter and itsmechanism is wholly supported from the tractor.

The main object of the invention is to mount a direct connected corn planter on 'a tractor so thatthe entire weight of the planter frame struc--. ture and mechanism, when transported, will be carried by the tractor. Another object is to connect the covering wheels to the planter, which also serve as the gage wheels, so that they will support part of the weight of the planter as the operator begins to raise the planter into transport position.

Another object of the invention is to provide the planter attachment with quick detachable features so that it may be readily attached and detached from the tractor.

Still another object of the invention is to provide driving power for the planter mechanism from the rear axle of the tractor.

Another object of the invention is to throw out the doffer mechanism upon the raising of the planter to transport position.

Still another object of the invention is to throw out of .gear the planter mechanism upon raising the planter to transport position.

A further object of the invention is to provide adjustment for various row. spacings of the 30 planting units. I

Still another object of the invention is to provide means for using the planter over terraces.

In the construction illustrated, the tractor of a well-known tricycle-type 'hasan oblong casing forming the rear end of the tractor body and containing the transmission and differential mechanism. The rear portion of .this casing has bolted, -or otherwise secured to it, on each side, the aligned tubular axle housings 2| containing the bearings for the axle shafts 22 which extend beyond the ends of the housings. Traction wheels 23 are adjustably necured to the axle ends. The casing 20 supports the centrally located driver's seat 24 in convenient relation to the usual steering wheel 25 and other controls, not shown. The casing 20 has suitable hearings; in' its-lower portion for the central power take-off shaft 26 'which projects from the rear wall thereof and is driven through suitable gearing within the casing, and by means of the power take-01!, closely coupled implements requiring power may be driven therefrom. Cast integrally on the axle housings 2| are the inner and outer flanges 21 and 28. Secured to the inner flanges 21 are the coupling members 25 to which the quick detachable planter is attached. The coupling members 29 are disclosed in a copending application of Carl W. Mott, Serial No. 29,938, filed July 5, 1935.

In the present invention, the supporting structure'for the direct connected tractor planter consists of two downwardly extending right and left I hand members 30 and 8|, respectively, connected to the coupling members 29 by the usual quick; detachable coupling means as disclosed in the previously mentioned copending application of Carl W. Mott. c

The supporting members 30 and 3| have formed integral therewith, forwardly projecting portions 7 32 which are slotted to permit the passage of the securing bolts 83 of the coupling members 29. The forwardly extending members 32 also act as a guide and support for the planter attachment when it is being attached to the tractor. Similarly, the supporting members 30 and 3| are attached to the. coupling members 29 by other securingimembers 34 pivoted thereon which pass through slots in the outwardly extending legs of the supporting members 30 and 3|. Secured to the bottom of the downwardly extending supporting members 30 and 3| respectively and inclined or extending rearwardly and upwardly are the right and left hand supporting members 35 and 38 which are secured in spaced apart relation at their upper ends by the spacing member 31. To secure the supporting members 35 and 38 in their correct alignment with the tractor, the downwardly and rearwardly extending right and left hand braces 38 and 39 extend from the supporting members 38 and 3| to the attaching member for the spacing member3l. These supporting members provide an overhanging means or boom structure. Plvoted at the lower ends of the supporting members 30 and 3| respectively are the rearwardly extending right and left hand frame members which are pivoted to permit the vertical adjustment of the planter attachment secured thereto and which will now be described, Secured at the rear of the longitudinally extending members 48 and 4| are the front and rear transversely extending frame members 42 and 43 respectively. The front and rear frame members 42 and 43, respectively, are securely braced by the forwardly extending braces 44 and 45 connected at their front ends respectively to the longitudinally extending frame members 40 and 41 and at their rear ends to the downwardly extending bracket members 46 and 46',- and 41 and 41' secured to the front frame member 42 and the rear frame member 43, respectively. Secured at the outer right and left hand ends of the transversely extending frame of the planter are the right and left hand check wire guide and dofier mechanisms 48 and 49 respectively which are best shown and disclosed in the patent to R. L. Ford, 1,376,522, granted May 3, 1921. The longitudinally extending frame members 48 and M are secured to the front transversely extending frame member 42. by downwardly extending supports similar to the right and left hand supports 50 and 5! which secure the rear ends of the frame members 40 and 4! to the rear frame member 43. The frame members 42 and 43 are further braced by the longitudinally extending right and left hand brace members 52 and 53 which act as a support for the bearings 54 which rotatably support the transversely extending rockshaft 55 which carries the usual check wire forks 58 to engage the usual check. wire buttons when the planter is used as a check row planter. The ends of the transverse rockshaft are suitably supported in the bracket members of the check wire guide and doftlng mechanism. Pivotally mounted at each end of the transverse frame of the planter are the right and left hand marker bars 51 and 58 pivoted to the supporting brackets 41 and 41.

The marker bars 51 and 58 are braced by the pivoted braces 59 and 68 which are pivoted at their upper ends to the marker bars 51 and 58 and at their lower ends to brackets 6| and 82 secured to the front frame member 42. These marking bars 51 and 58 may be raised and lowered in the usual manner, in that as one marker bar is raised, the other is lowered and vice versa by having a rope connecting the two together.

The usual seed dropping mechanism including the hopper with its revolving seed planter and the furrow opener are adjustably mounted on the transverse frame members 42 and 43 so that the seed may be sown in rows, the spacing of the rows being from 28 to 44 inches. It is to be understood that the spacing of these units may be extended further, but the. spacing from 28 to 44 inches is the distance usually encountered in drilling while in check row planting the usual spacing is from 32 to 44 inches. The right and left hand planting units 83 and 84 are symmetrically mounted about the longitudinal axis of the planter which is a continuation of the longitudinal axis of the tractor. Units 63 and 84 consist of the seed hoppers 85 having their seed plates driven through suitable gearing from the transversely extending drive shaft 66. Each hopper and its mechanism is supported on a seed boot 8! which in turn has extending portions 68 and 88' for securing the boot and its mechanism to the front and rear transverse frame members 42 and 43, respectively. Through the supporting bracket 68 of the seed boot'the planter units 83 and 88 may be adjusted laterally on the transverse members 42 and 43. The runner or furrow opener 88 is attached to the bottom of the seed boot 6! at its rear portion and at its forward portion the runner 89 is supported by braces 10 and I8 attached to the bracketportion of the seed boot 81. The seed dropping mechanism within the seed boots 81 may be similar to the mechanism disclosed in the patent to Dennis 1,725,446, granted August 20, 1929. Suitable fertilizing units II and 12 are symmetrically placed as the planting units 63 and-84 and these also may be adjusted laterally for the various row spacings from 28 to 44 inches. The fertilizer units H and I2 consist of the usual fertilizer hoppers 13 with their feeding mechanism driven from the transversely extending drive shaft 14. A flexible tube 15 connects the fertilizer hoppers 13 with a fertilizer depositing unit 18 attached to the rear of the seed boot 61. Thefertilizer units and their depositing unit 16 may be similar to the mechanism disclosed in the patents to Kriegbaum et al. 1,921,885 and 1,921,886 granted August 8, 1933, The crank arm ll of the fertilizer depositing unit is connected by a link 18 to another crank arm secured to the check row shaft 55 of the planter. In this manner as the planter mechanism is operated through the check row shaft 55 the mechanism of the fertilizer depositing unit 18 operates ;and 84 andthe fertilizing'units ll and 12. The depth of the planter is ga'ged by gage wheels or means 19 which are symmetrically placed about the longitudinal axis of the planter and trail behind the furrow openers 89 of each planter unit and act as covering wheels forthe furrow left by the furrow opener and fertilizer depositing units 69 and 18, respectively. The gage wheels or means '18 are pivotally mounted for adjustment in a vertical plane by the longitudinally extending right and left hand wheel supporting arms or means 88 and 8l. The gage wheels 18 are rotatably mounted on a transversely extending portion and 8| of the wheel arms 80 and BI. The wheel arms 80 and 8| are pivotally supported on the front frame member 42 by the supporting brackets 82 and 83 through which the inne'r extending transverse portions 88" and, 8|" are Journaled. The supporting brackets with their wheel arms 88 and Bi may likewise be adjusted laterally according to the row spacing of the planter units 63' and 64 and the fertilizer units H and 12. As best shown in Figures 5 and 7, the gage wheels 18 are adjusted simultaneously by means of the adjusting lever 84 secured to the transverse rockshaft 85. The lever check fork shaft 55 and the transverse drive shaft 66. The rearend of the adjusting quadrant 8B is supported by a brace 86 secured to the quadrant and to the rear frame member 43. Adjustably mounted on the transverse rockshaft are the rearwardly extending crank arms 98, as best shown in Figures 4 and 5. The crank arm 88 comprises two rearwardly-extending members 88' and 89" having their forward ends notched and engaging the transverse rockshaft 85 and passing through slots in an angular supporting member 89. The angular supporting member is secured to the rockshaft 85 by-the U-bolt 90. The U-bolt 90 when it is tightened by the nuts thereon clamps the members 88 and 98 securely to the rockshaft 95 by means of the clamp supporting member 89. Pivotally mounted at the rear ends of the crank members 88' and 88" is a wheel arm engaging member 9i which acts as the adjusting lever 84 is moved rearwardly to engage the wheel arm 80, as shown in Figure 5 to adjust the planter furrow op'eners 69 upwardly'or to a shallow planting depth. As the adjusting lever 84 is moved forwardly the furrow openers 69 are adjusted to a deeper planting depth. The wheel arm all, as it is pivoted to the front frame member 42, has an arched portion to extend over the top of the rear frame member t3 which is lower than the front frame member 132. It is thus seen that when the planter frame is raised by a master lever 92 for transport, the operation and mechanism of which will be described later, the wheel arms 8% with their 7 corresponding gage wheels 19, as they are pivoted to the front frame member t2, they will remain on the ground detached from the members ti until the transverse frame of the planter has been raised a sumcient' height for the rear frame member iii to engage the under side of the wheel arm Bil to simultaneously raise the gage wheels 19 for transport position. Since the wheel arm engaging member 9! only engages the top of the wheel arm 80, there is thus formed a lost motion connection between the crank arm 88 and the wheel arm til so that the weight of the planter frame'acts to cause the wheel arm engaging member to engage the wheel arm Btfonly when the gage wheels 19 are engaging the ground and when the adjusting lever 84 is adjusted rear- -wardly. When the adjusting lever 84 is in .its

rear frame member engages the underneath portion of the respective wheel arms 80.

The fertilizer units II and 12 .are supported transv rsely on the planter by a transverse extending frame member 93-, as best shown in Figures 2 and 4. Supporting brackets 94 are adjustably mounted on the transverse member 93 for supporting the fertilizer units H and 12 re- 2,172,980 "84 is secured in adjusted position by the" usual spectively in their respective adjusted positions according to the row spacing of the-planting units 63 and 64. The transverse member 93 is secured by right and left hand supporting brackets 95 and 96 to the rear ends of the longitudinally extending frame members 40 and 4| respectively.

As best shown in Figures 1, 2, 3, and 6 the planter frame and its mechanism is raised from its trailing planting position to transport position'by the master lever 92. The master lever 92 is secured to a transverse rockshaft 91 extending between the rear portion of the frame members 40 and 4| and journaled on the respective supporting brackets 98 and 99 secured to the frame members 40 and 41 respectively. The supporting bracket 98 has formed thereon an adjusting quadrant 98' about which the master lever 92 is adjusted in the usual manner by the usual thumb latch rod and detent. The adjusting quadrant 98', as best shown in Figure 6, has only two adjusting positions, the position as shown in Figure 6 with the adjusting lever 92 vertical which is the workingposition for the planter, and in the position as shown in Figure 3 with the lever 92 extending forward to a position across the rear axle of the tractor which corresponds to the raised or transporting position of the planter attachment Secured to the mid-portion of the transverse rockshaft 91 is a forward and rearwardly extending integral crank arm Hill. Pivotally secured to the forward endof the crank arm N10 is a -lifting link Illl slidably mounted in a pivoted bracket M12 journaled in the rear ends of the rearwardly extending supporting members 35 and 36 respectively. The crank arm MU has several adjusting holes for the link till so that the mechanical advantage of the lifting lever may be adjusted. In order to allow additional adjustment in case the planter attachment is used to plant over terraces, the adjusting member 13 which is slotted may be removed from the link llli thereby permitting the planter attachment to'have approximately 8 or 10 inches greater vertical movement so that as the wheel of the tractor rides over the ridge of the terrace the planter runner 69 will still engage the ground. This adjustment 'is only needed when the planter is used over terraces as the length of the link I0! as ordinarily used is suflicient always to allow the planter attachment runners to engage the ground. The rear end we of the arm M0 has a pivoted link ma which is connected at its forward end to a spring I05.

The spring we is connected at its forward end .to a front cross'member 16 secured at each end to the longitudinally extending frame members 40 and M.

195 is to counterbalance the weight of theplanter attachment in order to aidthe operator when lifting the planter attachment to transport posi- 99'. As the lever 92 is pulled forwardly, the for- The tension of the spring Hi5 may .be adjusted in the usual manner by the .threaded vlink member I01 connecting the spring to the cross member I96. The function of the spring wardportion of the arm I00, which is secured to bracket I02 is mounted are fixed, and the distance between the bracket I02 and the point of attachment of the link "I to the arm I00 cannot change, downward movement of the forward end of the arm I00 causes an upward movement of the planter attachment; In this manner the planter attachment is allowed to be raised in a vertical plane about the lower ends of the supporting members 30 and 3| to which the forwardly extending frame members 40 and H of the planter attachment are pivoted. Relative movement or lost motion of the link IOI with respect to the stationary supporting frame is provided through the pivoted bracket I02 supported in the frame members and 36. This will permit the implement frame to freely follow the contour of the ground in the ground engaging position. It is thus seen that a simple lift mechanism has been provided integral with the planter attachment for raising the planter frame vertically with re-'- spect to its supporting frame secured to the tractor without having any rockshaft or other additional raising and lowering devices secured to the tractor frame. The planter attachment as disclosed with its raising and lowering mechanism provides a compact unit which may be readily detached or attached tothe tractor by the adJust ing of the securing members 33 and 34.

As the planter attachment is raised to transport position by the operation of the lever 92, the crank arm I00, as it moves downwardly relative to the planter frame, engages a spring member I03 which is secured at both ends to links I I0 and III respectively. These links H0 and III respectively are pivotally connected to pivoted link members I I2 and H3 which in turn are pivotally mounted on the frame members 40 and M. The links I I2 and H3 have pivotally connected there- .to transversely extending links I I4 and I I5 which are connected to the doiiing mechanism of the check wire guides 43 and 40 in the manner shown and disclosed in the patent to Ford 1,376,522, May 3, 1921. It is thus seen' that, as the planter attachment is raised, the crank arm I00 engages this resilient connection I30 causing the links I I4 and II5 to release the dofling mechanism of the check wire guides 40 and 49 which in turn allows the check wire which happens to be mounted in either of the check wire guides 43 or 43 to be released.

Supported at the lower end of the supporting member 30 is the transversely extending planter shaft while the other clutth' member I22 is allowed to revolve freely on the Jack-shaft H1. The clutch members I2I and I22 are thrown out of disengagement by the clutch throw-out member I23 slidably supported in the bracket I24 secured to the supporting member, (Figure 2).

The throw-out member I23 has a laterally extending portion on its upper end which is so positioned on the attachment as to be in the path of movement of the lever 32 and is engaged thereby to be moved downwardly. The clutch members III and I22 will thus be disengaged from each other hen the lifting lever 32 is in the position. as she in Figure 3 so that, as the planter is raised to trans-v port position, the drive mechanism of the planter is simultaneously and automatically thrown out of operation. If the operator desires to throw out the clutch members without lifting the planter attachment, the throw-out fmember I23 is near enough to the operator's station to enable him to depress the upper end thereof and throw out the same independently of the lifting mechanism. Secured to the clutch member I22 are a plurality of sprockets I25, I26, I21, and I28. The drive sprockets I25, I26, and I21 are used to drive the planter mechanism at speeds proportionate to the forward travel of the tractor. The drive sprocket I28 is used to drive the fertilizer attachments II and 12. The planting mechanisms of the planting units 63 and 64 are driven from the sprockets I25,=I26, or I21, through the chain drive I29 driving the sprocket I30 of the clutch mechanism I3I on the planter drive shaft 66. The planter clutch mechanismI3I is shown diagrammatically and may be of the type disclosed in the patent to Dennis 1,543,603, granted June 23, 1925. The check fork shaft is operatively connected to the clutch mechanism I3I as disclosed in the aforesaid patent to Dennis. The fertilizer 'mechanismof the fertilizing units 1! and 12 are driven from the sprocket I23 through the chain drive at I32 to the driven sprocket "I33 on the fertilizer units drive shaft 14. It is to be understood that suitable chain tightening mechanism may be used 'to adjust the tension of the respective chain drives IIS, I29, and I32. The chain I28 may be changed from one sprocket tothe other of the drive sprockets I25, I26, and I21. As shown in Figures 2 and 3 the number of seeds dropped by the planting units 63 and 64 may be adjusted by the lever I34 which is pivotally and longitudinally mounted between the front frame member 42 and a supporting quadrant I35 on the rear frame 43, as best shown in Figure B. A detent I36 engages notches I31, corresponding to the number of seeds to be dropped in each hill. Upstanding fork members I30 engage the yoke member I39 on the revolving planter mechanism drive shaft 66. The lever I34 with its detent I36 is resiliently held in place by the spring 0 on the longitudinally extending pivot portion I34. of the lever I34. With this construction the'shaft 66 may rotate at all times and still be adJusted axially transversely of the planting units 63 and 64 so that the seed plates may be revolved proportionately to the number of seeds to be dropped in'a hill which is old in the art and is best disclosed in the patent to Englund 918,983 granted April 20, 1909. The shaft 63 has two combination gears 66a and'66b, each of which has two kinds of gear teeth. Gear teeth of the same kind on the respective gears are thrown into play with their respective planter units upon operating the lever I34.

As shown in Figures 2 and 9 the latch device for locking the valve mechanism of the planting units 63 and 64 is operated so that the planter units 63 and 64 may be used to drill instead of being used as check row planters. As best shown in Figure 9 and disclosed in the patent to Dennis 1,725,446, above cited, the lever I4I which is pivoted to a bracket I42 supported on the rear frame member 43 has pivotally mounted thereon a link I43 .with a slot I44 formed by bending over a portion of the link I43 upon itself. The slot I44 forms a lost motion connection between an upstanding crank arm I45 secured to the check fork shaft. 55. The slot I44 permits the check fork shaft 55 to oscillate when the planter attachment is being used as a. check row planter. When the lever 1 4| is pulled rearwardly the mechanism on the check fork shaft 55 which engages the clutch mechanism i3! on the planter drive shaft 66 is thrown out of engagement with the clutch mechanism l3! so that the mechanism of the planter'unit 83 and 64 may be continuously driven so that the planter will continuously drill the seeds instead of dropping them in spaced hills as when the check fork shaft mechanism engages the clutch Hit." The lever I 4| when pulled rearwardly forms a toggle lock to lock the check fork shaft 55 out of engagement with the clutch member 13!. At the same time the check fork mechanism is held out of engagement with the clutch member i3l, the valve mechanism in the seed boot is also held in. position fordrilling. It is to be understood that the spring tension-of the check fork shaft 55 may be adjusted in any usual manner, as shown in the patent to Van Der V'iiet 1,667,362, April 24, 1928. The spring tension means for returning the check fork shaft 55,

after it has'been moved by a button on the check wire, comprises generally a spring 55a connected to an arm 55" fixed to. the shaft 55 and to an adjustable holder 55b longitudinally slidable in a slot in a depending bracket 550 on the rear frame. member d3, Figures 4 and 9.

As best shown in Figure 2, the check wire it may be wound upon the reel 14'! after the field has been planted, by means of the friction wheel Mt engaging the covering wheel E9. The fric tion wheel M8 is secured to the reel shaft I49 which is journaled in a bearing ibb at the inner end which is, in 'turn,'supported in the longitudinally extending supporting member l5i. The supporting member lbi is passed through either vertical slot I52 located in brackets Eli and ti on 1 the rear frame member d3, depending upon which side of the implement the reel is to be placed, and

forwardly through a slot in a bracket on the front 5 bers t2 and d3 of the planter by means'of a link ifi i attached at its front end to the supporting bracket and at its rear end to a bearing H5 in which the reel shaft M9 is journaled. In reeling, unreellng, and in transport, the reel and shaft are supported as shown in Figure 2. How ever, after the check-wire has been laid out prior to planting, the reel and its mechanism is removed and laid'to one side until after the field has been planted when it is again attached for reeling up the check-wire and to transport the same. As the gage wheels i9 and the supporting brackets 50, Si, 52-, and 53 are symmetrically placed the reel and its mechanism may likewise be placed opposite to the position shown in Figure 2 so that the'reel may be operated to take'up the check,

wire on either side of the planter attachment.

It is to be understood that the reel shaft I49- could "be driven in any other suitable" manner.-

It is also to be understood that the reel shaft and the planter mechanism and its fertilizer attachment could be driven from the power take-off shaft26. In winding the check wire-on the'reel m the latt ce W ee so r r rti neq that v attachment is lowered from its transport position, as shown in Figure 3 by the lever 92. 'Next the lever 84 is adjusted so that the gage wheels 19 engage the ground and are locked in position by the lever 84. Next a pivoted support I56 which is secured to the front frame member is locked so that it engages the ground as shown in Figure 1. The chain H9 is then removed from the sprockets H8 and I20. Next the pivoted bolts 33 and 34 attaching theupright support members 30 and 31- to the coupling members 29 are unloosened and swung out of position. The tractor may then be driven away and it is ready to be attached to any other quick detachable implements. It is to be understood that the planter attachment may be readily attached to the tractor by going through the previous operation in the reverse order.

As will be obvious to those skilled in the art, other implements can be attached to the implement frame structure which has been previously described or other forms of planter and fertilizer mechanisms may be used. It is also to be understood that other forms of lifting and lowering mechanisms may be used for raising and lowering the implement frame; and, a wide range of utility is therefore attainable to meet any requirement arising in connection with the implement frame and its planter attachment. It is further understood that materials suitable to the stresses encountered in a direct connected planter attachment of this nature are to be used. The preferred'embodiment of the invention herein described is capable of certain modifications without departurefrom the scope of the invention to be defined in the following claims.
